How to Use Dynamic Linking to Speed Up Rust Development Builds

Rust does not use dynamic linking to speed up development builds; it uses incremental compilation and Cargo's dependency caching. Dynamic linking is primarily used for reducing binary size or enabling runtime updates, not for faster compilation. To speed up your builds, ensure you are using the dev profile, which is unoptimized by default, and let Cargo handle dependency caching automatically. No special flags or configuration are needed for this standard behavior.

Rust builds are fast because it only recompiles the parts of your code that changed, not the whole project. Think of it like updating a single chapter in a book instead of rewriting the entire thing every time you make a small edit. You don't need to change how libraries are linked to get this speed; it happens automatically when you run your standard build commands.
